DELL PowerEdge R640 40-Core NVMe Rack Server 2x Xeon Gold 6138 512GB DDR4 H730

40-Core Rack Server for Virtualization

The Dell PowerEdge R640 is a 1U rackmount server built for business workloads such as virtualization, databases, file storage and application hosting. Two Intel Xeon Gold 6138 processors deliver 40 total cores at 2.00GHz for dependable multi-threaded performance. It targets IT teams needing dense compute in a standard rack form factor. Buyers who require GPU acceleration or workstation-class single-thread speed should look elsewhere.

H730 Controller and NVMe Bays

An integrated H730 storage controller simplifies RAID setup and daily management of the internal drive array. The chassis provides ten 2.5-inch bays, eight of which are NVMe capable, allowing high-speed flash configurations without extra adapters. Drives are not included, so you select capacity and endurance ratings that match your workload. Systems needing 3.5-inch drive support or external JBOD connectivity are not addressed by this configuration.

512GB DDR4 with 3TB Headroom

The server ships with 512GB of DDR4 memory installed across two processors, supporting multiple virtual machines and data-heavy applications immediately. Maximum memory capacity reaches 3TB when all DIMM slots are populated, giving ample headroom for future growth. Workloads exceeding 3TB of RAM or requiring persistent memory modules cannot be accommodated by this platform.
